On the detectability of quantum radiation in Bose-Einstein condensates — •Ralf Schuetzhold — Institut für Theoretische Physik, Technische Universität Dresden, D-01062 Dresden, Germany

Based on doubly detuned Raman transitions between (meta) stable atomic or molecular states and recently developed atom counting techniques, a detection scheme for sound waves in dilute Bose-Einstein condensates is proposed whose accuracy might reach down to the level of a few or even single phonons. This scheme could open up a new range of applications including the experimental observation of quantum radiation phenomena such as the Hawking effect in sonic black-hole analogues or the acoustic analogue of cosmological particle creation.
